    Fork oil change

    The oil that comes in those Chinese forks is just cooking oil, I swear. When I took mine out I could smell what smells like burned vegetable oil when you leave a pot of it on the stove until it's all gone. Makes such a huge difference, even if you don't change the level at all, just put some...

    YX150 clunking noise

    Hi all, just wondering what the most likely culprit in a YX150 engine would be for making a ticking noise, would it be likely to be the cam chain slapping or the big end bearing on the conrod? A mate with a big screwdriver used as a bush-mechanics stethoscope decided it sounded like it was...

    YX140 head gasket

    Tight, but not so tight it snaps? Don't know exact torque settings for this engine but your arm is a better torque wrench anyway if you can feel when a bolt is going to snap. Just seat the nut fully and give it another 45 - 60 degree turn after it has seated, warm up and check that its still...

    Fork oil change

    Well, nothing WRONG with it, I just felt with my bike 7.5W would hold the forks a bit higher in the stroke, get just a touch too much sag with the 5W, and seeing as there's no other way to adjust it, heavier oil is the go, screwing with the oil to air ratio by taking out oil will not help the...

    Fork oil change

    15 weight engine oil is about equivalent to 0W fork oil. Different viscosity ratings for the oil. Don't use engine oil in your forks, get some Motorex Racing Fork Oil 7.5W, as its actual viscosity rating is about 35 cSt at 40degrees celsius, about the weight you are after in a pit bike...

    Suspension Upgrade

    Does anyone know whether a set of triple clamps / forks / wheel from a KX 65 / RM 65 would fit in the frame from an Atomik Bigfoot? My uncle's little 125's forks are stuffed, been told you can put a KX 65 front end on it, including the wheel as the forks are wider, just looking for...

    new to pit bikes

    My mate has a DHZ 150 and a motovert 125, I've got an atomik 140, atomik 250 and another real crap atomik 125. The motovert has the smoothest motor of all of them, and is still powerful enough for you to just twist the throttle more once you build some confidence back. Thing I like about...

    Atomik USD fork seals - where to buy

    It seems to be OK now after a clean with camera film. . . So is 150ml about the right amount of oil to chuck back in? It lost a LOT of oil before I fixed it, so a complete refill is on the cards for sure.

    Atomik USD fork seals - where to buy

    OK, so I just broke a camera and did what you said. I had tried cleaning them with a $20 note before, just wasn't told to jump up and down on the forks, hope that worked with the camera film, but regardless, if anyone knows which brand fork seals and what size they are I'd still really like...

    Atomik USD fork seals - where to buy

    Hi, I have an Atomik 140 Bigfoot, left fork has lost almost all its oil to a leaky fork seal, can anyone help me find where to get fork seals to fit? All atomik say about them is "740mm USD forks", no mention whatsoever of brand. Going to get some DNM hornets later on anyway, so please...
